My Openhab - Jetty Request Failed: null

This issue is driving me crazy and i am not sure that the severity is understood.
so, i will summarize. @Kai, once again the reliability of the android application and iOs is affected

When using the android application with a connection to myopenhab, some warnings are logged and the android application UI is not refreshed.

[WARN ] [io.openhabcloud.internal.CloudClient] - Jetty request 1379803 failed: null
[WARN ] [io.openhabcloud.internal.CloudClient] - Response Failure: null

Movie issue

Github issue

How can i debug a such issue?

it’s not possible to increase the log level for io.openhabcloud.internal.CloudClient, it’s not a binding

This issue was raised in several threads and it affects the android and iOS users:

I want to underline that in my current case, the sendnotifications do not work also
